Title: Improvements in and relating to control devices for winding engines and the like
IPC: B66B5/08
Filed: 1924-06-13
Abstract: 239,913. Graham, A., and Fullerton, Hodgart, & Barclay, Ltd. June 13, 1924. Mechanical telegraphs; mine and colliery signals.-In control devices for colliery winding engines which actuate automatically the brake engine or throttle valve when the speed exceeds either the maximum speed for material or for men, the signalling apparatus is provided with means connected with the control device by which when the third impulse of the " men " signal is completed, the speed at which the control device operates is reduced automatically to the maximum speed for men. A shaft 1 driven by the engine is connected by bevel gears 6 with a governor 5 and by worm gear 4 with a shaft 3. The sleeve 5<a> of the governor is engaged by a lever 10 which is connected by arms 9 to bars 8 arranged on opposite sides of the shaft 3 and connected to a roughened stepped cone 7 slidably but non-rotatably mounted on the shaft. A disc 11 provided with two similar cams 12 is mounted on the shalt 3. The cam surfaces are formed by blade springs 32 which are kept in place by trigger levers 33 provided with screws 34. A roller- 13 resting on the edge of the disc is carried by a rod 15 mounted at one end of a lever 16. One. arm of a floating lever 19 pivoted to the lever 16 is connected by a link 21, bell-crank lever 22 and a pin or other trigger device to a weighted lever 20 connected to the brake engine or throttle valve. The other end of the lever 19 carries an eccentrically-mounted roller 24 having a roughened periphery. The cams are so placed on thedisc, and the gearing 4 is of such a ratio, that during one wind the roller 13 runs from the high end of one cam to the corresponding end of the other. When the roller is on the disc the engine runs at the full permitted speed, but speed is reduced gradually as the roller ascends either of the cams. 'When the engine starts, the governor sleeve 5a rises and the cone 7 is moved along the shaft 1. At the same time the inward movement of the roller 13 causes the removal of the roller 24 from the path of the cone 7. At full speed the edge of the roller 24 is adjacent to and in line with the largest part of the cone 7. If the speed increases the cone engages the roller 24 and rotates it. This movement of the rollerrocks the lever 19 and thereby causes the withdrawal of the pin 23 from the lever 20 and the operation of the brake, engine or throttle valve. A pin 28 on the arm 27 of the lever 10 works in a slot 29 in a weighted arm 30 which is supported by a pin 31 when material is being raised &c. When the signal to raise men is given, a pointer on the signalling apparatus moves outwards and establishes electrical connections by means of which a magnet withdraws the pin 31. The weighted arm 30 then rests on the pin 28 and counterbalances the governor spring &c. so that the governor sleeve moves to its highest position at a lower speed. The point of release of the trigger is adjusted by moving the screw 34. Specification 192.114 is referred to.

Filed: 1923-06-01
Abstract: 221,004. Wood, L. E. June 1, 1923. Controllers, locking; controllers with no-volt and overload release.-Relates to change-over starters, such as are used for alternating current motors, of the kind in which the change-over member, is prevented from being moved direct from the "off" position to the "running" side by a catch mechanically connected to an overload or no-volt release. According to the invention the catch. is. constituted by a projecting part of the overload &c. trip-lever, which is moved by the wiping action of a triangular cam on the change-over spindle. An additional temporary support and a spring bias for the catch and release lever may increase the sensitiveness of subsequent automatic releases. Fig. 1 shows the essential parts of the invention in its simpler form. A square spindle A carrying the change-over member is fitted with a triangular cam P which, from the position shown, cannot move to the right of a projection L<3> on the underside of a long lever L. After movement to the left, the cam in its return passage wipes under an inclined face L<2> and then clears the raised catch if the movement is rapid, and takes up the "running" position, where it is retained by the same catch engaging the opposite side of the cam. The free end of the lever L remains down unless raised by a no-voltage release member V or an overload release member O.

Filed: 1972-03-28
Abstract: 1387712 Modulating light ; television PHILIPS ELECTRONIC & ASSOCIATES INDUSTRIES Ltd 28 March 1972 [31 March 1971] 14515/72 Heading H4F [Also in Division H1] An electro-optic device includes an optic image relay comprising a photo-sensitive layer 16, a plate 1 exhibiting voltage-dependent double refraction and maintained near its Curie temperature, and electrodes 3, 17 connected to a direct voltage source, modulated light radiation being directed on to the photo-sensitive layer 16, and polarized light radiation being directed on to plate 1. As shown an insulating reflecting layer is provided between plate 1 and layer 16 and reflects the polarized light through analyser 32. Layer 16 may be of photoconductive material, In another embodiment a layer of secondary-emission material is provided in place of layer 16, electrode 17 is replaced by a grid spaced from the surface of the secondary emission layer, and a photo-cathode is provided on the inside surface of window 8. Modulated radiation beam 23 may be derived from a flying spot scanner or from a laser, or may be an image projected from a scene or from a cathode-ray tube screen, or may be a coherent light image, a Fourier transform or a hologram. Successive images projected on the photosensitive layer are added whereby the contrast between recurrent and non-recurrent parts of a series of images may be increased. If the voltage across the device is reversed between two series of images the resulting display represents the difference between the two series. Identical parts of two series of images may thus be eliminated, e.g. fixed echoes in radar. If light source 30 produces coherent light a phase transformer introducing a constant subtractive phase shift may be provided which, if the phase shift is such that the average transmission of the assembly is zero, enables the zero diffraction order in the Fourier transform of the image to be omitted. If the phase shift corresponds to that of the most illuminated part of the stored image the displayed image is a negative of that image. Similar effects may be obtained by reversing the polarity of the applied voltage and exposing the photo-sensitive layer to uniform illumination of appropriate intensity following exposure to an image. When a photo-cathode and a secondary emission layer are used operation is asymmetrical with respect to the relative polarities of the grid and the photo-cathode and the relative intensities of the light beams employed before and after reversal of the potential have to be taken into account. A light amplifier comprising a photo-cathode and a layer of luminescent material may be used to amplify the incident light beam. The intermediate electron beam formed in the embodiment of the optic relay including the photo-cathode and the secondary emission layer may be amplified using a microchannel amplifier. Reference has been directed by the Comptroller to Specification 1,102,936.

Abstract: 1,208,447. Impregnating electrical windings. G. E. WILDING. 25 March, 1968 [30 March, 1967], No. 14686/67. Heading D1P. A plurality of coil windings are successively trickle-impregnated with polyester resin by step-by-step circular passage on a rotary carrier past a resin-impregnation station, the windings being heated by a variable heating current at index positions before and after impregnation and rotated comparatively slowly before and after impregnation and comparatively quickly during impregnation. The rotary carrier comprises a pair of annular discs 8 and 9 which are connected by spacers and have bearing spindles for rotation around the periphery of a stationary drum 5 in addition to armature-carrying spindles. Resin is fed to the winding leads of a series of armatures at the first of two feed positions via a pump 48 and to opposite ends of the armatures at both feed positions via a pump 49. The pumping time may be varied (Fig. 10). Electric heating is effected by a plurality of current supply brush assemblies (Figs. 3 and 7, not shown) at index positions A1 to F3. Rotation of the armature-carrying spindles is effected by a system of sprocket wheels and endless chains (Fig. 5, not shown). Rotation of the rotary carrier is effected by intermittent rotation at regular intervals of a star wheel which engages each armature-carrying spindle in turn (Figs. 6 and 8, not shown). The whole apparatus is tilted forward at an angle of about 2‹.
